To all whom it may concern;

Be it known that we, Mnnnvm E. Enron- SON and ARTHUR lV. Mocnnn, citizens of the United States residing at Grantsburg, in the county of Burnett and State of Wisconsin, have invented certain new and useful Improvements in Sack-Holders, of which the following is a specification.

. Our invention relates to sack holders, the primary object of our invention being the provision of a sack holder upon which the sack may be readily mounted when it is to be filled and from which the sack may be removed when filled without any material effort, no lifting of the sack and contents being necessary.

A. further object of our invention is to provide a sack holder which may he adjusted'for use with various sizes of seeks, including sacks of difierent lengths as well a A still. further object of our invention is to construct a sack holder so arranged that. theseck is yieldably held with its mouth open and elevated in such a manner that the sack either rests at its lower end upon a support or is held slightly above the suport. A still further object of our invention is to provide a sack holder which shall be simple and economical in construction and at the same time efficient and durable in operav tion.

With these and other objects in View, our

invention will be more fully described, illusing the same in operation; Fig. 2 1s at top plan view of the sack holder, showing the sack supporting .arms in activeposition in full lines, a sack being shown 111 place by dotted lines and the inactive position of the sack holding arms being also shown in dot ted lines; Fig. 3 is an end view of the sack holder; Fig. 4 is a fragmentary sectional view taken on the line H of Fig. 3 and illustrating the manner in which the scale holding arms are mounted in the frame; Fig.-

- 5 is a sectional view on the line 5- 5 of Fig. 3, showing themeans provided for vertical adjustment of the sack holder; Fig. dis a portion 24- which extends within the nemben lit) perspective view of one of the sack engaging hooks.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters,

i The preferred embodiment of our inventron consistsprima'rily of a supportingbase or platform 10, frame 11 and seek holding arms 12, the frame extendin vertically from the base and the sack hol jng arms bein swingingly mounted at the upper end o the frame.

.Mo're specifically the base, which is preferably rectangular in 'shape,'is usually constructed from a plurality of boards 13 secured together at their ends by cleats i4 nailed or otherwise fastened to the lower faces of the boards and serving not only ss' a means for securing the boards together, but alsces sup fin-ting feet to hold the filatform in slight y raised position above'the floor. The frame 11 includes a pair of vertical spaced apart telescop c standards, each of which-is formed of-two main members 15 and 16, both of these members being tubular in construction. Metallic piping is usually employed for this frame and the lowermost of these members; that is the member 15,'is threaded at its lower end to engage in the threaded socket 17 secured to one of the cor-.

hers of the platform. The upper end of this member 15 isexternally threaded to receive the internally threaded tapered cou ling 18. A rod 19 extends at its ends into t e upper end of the member 15 and the lower end of the member 16, being edjustably secured is Provided at its upper end. with a T-cou-* tally extending sockets of these T-couplings.

23 is threaded by its ends into the horizofu- V will be seen by reference to Fig. l, the flu-hove described frame extends vertically the upper portion thereof may be readily adjusted at various heights by proper manipulation of the wing bolt 20 and set n'ut21. 'The sack supporting arms 12 are swin ingly mounted in the upper ends of tlie treme members 16, each including};- a body i from the rear part of the platform 10 and I tion 2a of the arm having one and passed.

into a bore 29 formedfthereinfand the opposite end-30 extended into the cross brace 23 of the frame, the tendency of these springs being to'swing the free ends of the arms outwardlyjtan" \rearwardly with respect to the sack holder-Q, v

In constructing the sack holder, the frame membersl5 are mounted upon the piatform,

the connecting rods 19 adjustably secured therein and the frame members 16, carrying the T-couplings 27, adjustably mounted upon the upper ends of the rods 19. lhe body portions of the swinging arms 12 are then'extended into the frame members 18 until the openings 29 are in aline'ment with .the horizontal socket of the couplings.

Lengths of stiff resilient wire are then inserted through such sockets to seat at their ends in the bores 290i the arms 12 when the arms are rotated several times to wind the resilient wire about the body portions thereof to form the springs 28. The free ends of the spring forming wires are then inserted in the ends of the cross brace 23 of the frame and said brace applied. In addition to these swinging sack supporting arms, the cross brace 23 is provided adjacent each end with a sack en. aging hook 31.

Each of these hooks inclu es a shank 32 which 'is passed through the transversely disposed horizontal bore 33 in the cross brace 23 and threaded at its free end to receive a nut 34. The bill portions of these hooks extend at substantially right angles to the shank portions and are spaced slightly in front of the brace 23, as best shown in Fig. 2 of the drawings, the hooks being blunt to prevent tearing of the sack. The cross brace is preferably provided with a plurality of spaced squared bores or openings 33' in order that the hooks may be changed from one to the other to adjust the sack holder for use with sacks of varying widths. The squared shanks of the hooks hold them against turning.

In employing our improved sack holder,

the edge of the sack is first engaged by the hooks 31 in the manner shown in Fig. 1. The swinging arms 12 are then moved inwardly and the sack positioned upon the hooked terminals 26 thereof, in the manner shown in Fig. 1, the sack being put on the hooks from the bottom. The arms are then released and, due tothe action of the springs 28, swung away from each other to spread the mouth of the sack, this spreading of the sack preventing the same from slipping from the hooks of the cross brace. As soon as the sack has been filled, the arms are swung inwardly to permit disengagement of the sack from the hooked terminals, such disengagement being readily accomplished as the bill portions of the hooks extend horisprings, when thus mounted, are housed and therefore protected and any danger of the sack supported upon the sack holder becoming caught upon the springs prevented. Furthermore, the construction and arrangement described is much simpler than other possible arrangements, such as mounting the springs'exteriorly of the standards and pro jecting one end of each spring through slots formed in the standards to engage the arms. Furthermore, with the arrangement disclosed, the springs serve to. hold the arms against accidental displacement from the standards, no other securing means for the arms being required.

Although We have illustrated. and described our sack holder in all its details, it will of course be understood that We do not wish to limit ourselves to the specific details of construction, as various minor changes, within the scope of the appended claims, may be made at any time, without in the slightest degree departing from the spirit of our invention.

Having thus described the invention, what is claimed as new is:

1, A sack holder including supporting ENE members, a cross brace connecting free ends of the members, sack supporting arms swingingly mounted in such ends of the members, and springs mounted in the members and cross brace and secured to the sack engaging arms to" normally hold the same with their I free ends away from each other.

2. A sack holder including tubular supporting standards, T-couplings upon the ends of the standards, a' transversebrace connecting the T-couplings, sack supporting arms swingingly mounted in the upper ends of the standards, those portions of the arms within the standards being provided with transverse bores, and helical springs sur-. rounding those portions-of the arms within the standards, one end of each spring ere tending th'mugh the bore of the adjacent arm and the opposite end of each spring ex-
